Power supply
The device is powered by an external 24 V DC power supply. It is not designed to be connected to a DC mains
supply.
▶
Before plugging in the device, ensure that the external power supply meets the required specifications (type K
to 61131-2).
External power supply (24 V DC)
Supply voltage
+24 V DC SELV (–15% / +20%)
Alternating current proportion
Max. 5%
The direct voltage level must not fall below 20.4 V.
Power consumption
Total max. 3.2 A at +24 V DC (1.2 A electronics; 2 A external I/O)
Energy buffering
10 ms
Internal power supply
A power supply for the system electronics for an input voltage of 24 V DC (–15% / +20%) is integrated into the
device. The power supply has integrated protection against reverse polarity and surge current protection (1.2 A).
Installation
▶
All connections and cables must be laid out so as to prevent inductive and capacitive interference causing any
damage to the device.
▶
Ensure that the infeed lines provide adequate current and voltage carrying capacity.
